Cooler Master MM831 Gaming Mouse Review

When you find a mouse that works well and feels right, you tend to stick with that mouse. At least for me, the longer I use a mouse, the less likely I am to ever stop using it. For me, that mouse is the G502. However, when I first got my hands on the Master Mouse MM831 from Cooler Master, I thought that this may be the mouse to replace my G502.  The Cooler Master MM831 is a hybrid wireless mouse with Qi-Charging capability. With the ability to run on Bluetooth, 2.4 GHz wireless, and through USB Type-C, the MM831 is an extremely versatile mouse. But the actual feel of a mouse can make or break the experience when using it, regardless of the feature set or software. Overall, the Cooler Master MM831 looks like a very well designed mouse. But, can it stand up to upwards of 8-10 hours a day of regular use? But more importantly, is it comfortable to use? We are going to answer these questions and more throughout his review. So, let’s get into it.
